Crunchyroll did not have a license for anything other than the United States and Canada (Sentai, the licensor, is a North American distributor). The regions were set wrong, and they corrected the problem.

When CR had the regions set wrong, they were streaming to regions they had no license for, so obviously they could not let it slide.

I guess I understand that, but is there any chance they'll get it for the UK too?

Or at least that it'll be released on DVD here sometime reasonably soon?

Crunchyroll would have to go back to the licensor in Japan and negotiate separate streaming rights for other regions. In some cases, a licensor may not be interested in only streaming rights (Sentai also obtained home video rights, for release in 2012), or the costs of setting up the contract for these other regions alone may not make it economically feasible.

No second season of Deadman Wonderland has even been green-lit (meaning don't expect it in January either), and likely never will be (DVD/CD sales in Japan have been poor). Unfortunately, the market in Japan doesn't always align with our tastes.
